29"

Let’s face it. You know what you want from your suspension, which is why we believe in giving our riders the options they desire. You’ll find that several of our forks are available in 29-inch models for riders who have a penchant for bigger wheels.

Air Guides™

We print Air Guides on all of our air-sprung forks. Maybe not a technological feat, but it will help you set up your suspension in seconds instead of minutes. And more time on your bike equals more chances to earn King of the Mountain on your favorite trail. Maybe they are a technological feat.

BOOST™

With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail and enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link. Which is why SRAM has developed an open standard with Boost compatible components for SRAM drivetrain, hubs and RockShox forks.

Bottomless Tokens

Bottomless Tokens allow riders to easily custom tune their RockShox fork’s air-spring performance to best match their own riding style and suspension preference. Adding the easy-to-install Bottomless Tokens changes the air-spring curve to resist bottom-out after a big hit, giving aggressive riders the power to attack the trail harder. Removing Bottomless Tokens makes the air-spring curve more linear, enhancing suspension feel for certain types of terrain or trail condition and ensuring riders who are less front-end aggressive benefit from 100 percent of their fork’s travel.

  • Black bottomless tokens are compatible with the following Solo Air forks: RS-1 SID, Reba, Bluto, Revelation.
  • Grey bottomless tokens are compatible with the following Solo Air forks: Pike, Lyrik, Yari, Pike DJ, BoXXer.
  • Dark red bottomless tokens are compatible with the following Dual Position Air forks: Pike, Lyrik, Yari.

Dig Valve

RockShox has redesigned the rebound piston to accommodate the Dig Valve, which provides the optimal level of control for both low and high speed compression, carefully controlling the oil flow to provide the rider with the right amount of support and impact absorption. The piston redesign allows the use of Rapid Recovery, a rebound tune that allows the shock to recover faster between consecutive bumps, for greater traction and a more controlled ride.

Maxle Stealth

Who knew we could make a thru axle disappear? The new Maxle Stealth offers a light, low profile alternative to Maxle Lite and Maxle Ultimate.

Maxle Ultimate

Basic things like axles are often the easiest to overlook. Put one hand on the Maxle Ultimate, though, and you’ll be glad we paid serious attention to the finer details. Because one hand is all it takes to remove or install the Maxle Ultimate. And lever-placement personalization is accomplished completely without the use of tools. Available for both front and rear, Maxle Ultimate is the easiest-to-operate axle system in the world. No tools, no worries, so you can concentrate on the trail ahead.

Motion Control DNA

Who doesn’t want more? As a mountain biker, more might mean more rocks, roots, and descents. More also could mean switchbacks, single tracks and steep ascents. The various configurations of Mission Control DNA were designed for those who want more out of their ride, and need more out of their suspension.

For the different riding styles there are four models of Motion Control DNA with Dual Flow rebound (exclusively available in SID and Revelation): XXRCT3RTL and RL.

XX - Designed for riders looking for more efficiency. 
The XX Motion Control DNA damper features RockShox’s XLoc hydraulic remote lockout for the lightest, most ergonomic go-fast solution.

RCT3 – Designed for riders looking for more bump gobbling performance. 
The new RCT3 damper features three distinct knob positions – Open, Threshold and Lock. The rider is able to quickly and easily access these three modes to manipulate damping performance for specific terrain:

  • Open for bump-gobbling performance
  • Threshold for efficiency and moderate bump compliance
  • Lock for ultimate pedaling efficiency

In addition to its three distinct modes, RCT3 features an independent adjustment of low speed compression.

RLT – Designed for riders who are looking for more stable ride. 
Featuring the adjustments of Motion Control – compression-to-lock with adjustable threshold updated with a Motion Control DNA spring tube and refined Dual Flow rebound.

RL – For riders looking for a more simple approach to suspension set up. The Motion Control DNA spring tube and refined Dual Flow rebound mated to compression-to-lock adjustability with a factory set threshold.

Power Bulge™

When you need your forearms to be stronger for more control, you bulk them up in the gym. When you need more durability from your fork, bulk them up with our Power Bulge. Other companies just increase the stanchion size adding extra weight. Power Bulge simply reinforces the lower leg to allow for an oversized bushing, increasing stiffness and maximizing your ride. Plus, it’s called Power Bulge.

Rapid Recovery™

Who doesn't want more available wheel travel for successive hits? The Rapid Recovery System allows the shock to recovery faster between consecutive bumps, letting the wheel track the ground with greater precision. This more active suspension system, doesn’t pack up and enables the bike to ride in a higher and softer part of the spring rate.  Rapid Recovery gives the rider access to more available wheel travel, bump after bump, to achieve a smoother and more controlled ride.

Sag Gradients™

Don’t set your sag correctly, and you might as well be hopping onto someone else’s bike. But why bust out plastic clips or rulers to keep your suspension fine-tuned? Our sag gradients are printed right on our fork’s upper tubes and shock damper bodies making perfect suspension setup easy and accurate. So give mom back her plastic clip and ruler.

Solo Air™

Solo Air is like a Buddhist monk. Its enlightened design lets you add air to your forks through a single Schrader valve, filling both the positive and negative air spring chambers simultaneously. So they’re always in perfect equilibrium, like Yin and Yang. Giving you a plush, predictable ride you can set up in seconds, with the lightest weight air spring on the market.

Torque Caps

Torque Caps make the bond between hub and fork dropout stronger, with an increased surface area connecting the two. This creates a stronger, stiffer interface, giving you a more responsive front wheel and more control. So you concentrate on the most important connection, the one between your bike and the trail.

XLoc Sprint™

Opposable thumbs let us do a lot of cool things. Rule over all the animals on the planet, climb to the top of the food chain, even invent the bicycle. And now they’re helping us kill it on the trail. This hydraulic lockout offers completely sealed and dependable lockout control through the click of an easy-to-reach button that can be triggered with a single thumb press. Press on to unlock, press again to lock. It’s just that easy. So next time you’re on the trail, remember everything those thumbs have done for you.

“The all new SID brings the fork back to its original roots, XC racing.” | enduro-mtb.com

“Reducing the travel to either 80 mm or 100 mm travel, the new SID could be designed with shorter and lighter upper tubes and air shafts, making it almost 100 g lighter than its predecessor.”

 

“Having ridden a number of XC focused forks, when testing the SID we were expecting good performance, but perhaps from a chassis that prioritizes weight over strength; we could not have been more wrong! “

by Moritz Dittmar, Enduro-mtb.com, April 26, 2016
RockShox SID | mtb-news.de | April 2016

“SID responses very well on the trail and gives great feedback. Even without Lockout you have minimum loss.”

 

“The new SID is stiff, very light and could totally convince us in the main discipline XC on our test trails.”

by Hannes, MTB NEWS, April 29, 2016
RockShox SID | mtb-mag.com |April 2016

“The lockout is miles beyond the old one. It’s firm and solid. Perfect for racing.”

 

“After turning off the lockout, the new SID changes its face. It becomes almost a smaller Pike. Small bump performance is excellent, as is mid-stroke support thanks to the Dig Valve. It’s exactly what you’d want from an XC fork: supple off the top and highly progressive through the travel.”

 

“We could never get the new SID out of its comfort zone, no matter how hard we pushed it”
